just tested with the latest hg(740a17139b67) - removed the whole mail directory,
then sent two mails, then retrieved them with POP3, then repeated sending and
retrieving. After each step cache file was updated(both after deliver and POP3 session).
Here are cached fields from idxview output after the test:
